Animals stratified to two groups, treatment and control. The treatment group animals (N. 25) were taken injectable antibiotic solution of Marbofloxacin manufactured by a Belgian company, 2mg/Kg, (1ml/50Kg body weight) IM for 3 days. The control group animals (N.= 25) were taken injectable antibiotic solution of Marbofloxacin manufactured by a French company 2mg/Kg, (1ml/50Kg body weight) IM for 3 days.
